Laser problems (not reading DVD media)
 

After opening my PS2, for some dust cleaning, and putting it back together i had problems with reading PS2 DVD games, DVD movies, DVD-R. Before opening everything was reading fine. And HDLoader is still working.

I opened it again, checked if every ribbon connected correctly. While i was frustrated and wanted to put everything back together, i broke the Reset/eject ribbon aswell, that's already fixed though.

I tried turning the white COG under the tray, I've cleaned the lenz with a CD cleaner. Anything else i could do before buying a new laser?

It's a SCPH-39004, so just don't want to throw it away and buy a new one.

Sorry I ddint get to your PM about this same question yet, but now that its a thread I will just reply here.

I'm not sure why a simple dusting would have caused this, but it is reading some CD based games right? Is it reading CD-R's PS2 and PSX? It may just need a little pot adjustment on on the back of the laser its self.

I know i PMed you first about it but i figured the more people see it the more could help and maybe others with the same problem could finally get theirs back going :)

I don't have any CD based PS2 games but it's reading PSX games fine and audio CDs work fine too. By pot, you mean those 2 little regulating resistors (potentiometers)?

Edit:
OK, i've found a site which one of the 2 is actually the DVD pot. http://www.cyber-mag.com/station/laserPS2.htm

Does anyboy with a 39004 know how much Ohms he/she has on the DVD pot?

Because mine was at 956 Ohms and the site says it should be around 1100 and 1400.

The 1100 and 1400 reading are what they would be from the factory. If your Pots are around 960 already this means that they have been turned down a little already. You might turn them down a little more to around 920 and see if this helps.

The pot farthest away from the white plastic worm gear is the DVD pot.

i turned it down to 913 with still no results.
